The first over-temperature protector 720 is not affected by the fluid flowing therethrough in normal use, however, when the first fluid inlet 110 or the first fluid outlet 230 of the first fluid passage 120 is blocked, the temperature of the fluid in the first fluid passage 120 will increase, and when the temperature of the fluid in the first fluid passage 120 reaches a first predetermined threshold, the first over-temperature protector 720 will cut off the power to the heating element 620; when the temperature of the fluid in the first fluid passage 120 is lower than the first predetermined threshold, the first over-temperature protection member 720 will re-conduct the power to the heating element 620, thereby effectively controlling the heating of the fluid in the first fluid passage 120 by the heater 600 and ensuring the safety performance of the hair drying device 10.
In the present embodiment, the first overheat protector 720 is disposed between the inner layer 610 and the heating element 620. Since the temperature of the fluid inside the heating element 620 is relatively more uniform, the first protector 720 can use the temperature of the fluid inside the heating element 620 as a temperature standard for controlling the power to be cut off or switched on to the heating element 620 by arranging the first protector 720 relatively to the inside of the heating element 620, thereby accurately controlling the heating of the fluid inside the first fluid channel 120 by the heater 600.
As shown in fig. 6, in an embodiment, the hair drying device 10 may further include a second overtemperature protection member 740. The second protector 740 is disposed in the first fluid channel 120 and is electrically connected to the heating element 620. The second over temperature protector 740 may be, but is not limited to, a thermal fuse. The second over temperature protector 740 is used to disconnect and cut off power to the heating element 620 when the temperature of the fluid in the first fluid channel 120 reaches a second predetermined threshold.
Further, the second predetermined threshold is higher than the first predetermined threshold. The second over-temperature protector 740 operates in case of failure of the first over-temperature protector 720, and when the temperature of the fluid in the first fluid passage 120 reaches a second predetermined threshold, the second over-temperature protector 740 will cut off the power to the heating element 620, thereby more effectively controlling the heating of the fluid in the first fluid passage 120 by the heater 600 and ensuring the safety performance of the hair drying device 10.
As shown in fig. 2, in one embodiment, the hair drying device 10 may further include a controller 800. The controller 800 is disposed in the second fluid passage 223. The controller 800 is electrically connected with the fan assembly 400 and the heater 600. The controller 800 may be used to control the heating temperature of the heater 600 and the rotational speed of the fan assembly 400. Further, the controller 800 is electrically connected to the temperature detector 700. The controller 800 may be configured to control the heating temperature of the heater 600 according to the detection result of the temperature detector 700.
As shown in fig. 2, further, in an embodiment, the hair drying device 10 further comprises a filter 900. The filter 900 is disposed in the bottom case 140 and connected to the inner case 130 to prevent large particles of dust entrained in the fluid from entering the first fluid channel 120 through the first fluid inlet 110.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
